摘要： A storage switch includes a first bitmap generator for generating a first bitmap, a controller for controlling copying of data, a first modifier, a second bitmap generator for generating a second bitmap, a second modifier, a merging controller for controlling to generate a third bitmap. When the writing of data is performed during the copying of data, the merging controller modifies a part of the index bits in the third bitmap corresponding to a part of the index bits of the first bitmap modified by the first modifier on account of the copying of data performed before the writing of data, and merges the second bitmap modified by the second modifier and the third bitmap modified by the merging controller. The controller resumes copying of data of any sub-regions on the basis of the merged bitmap.

摘要： In a hierarchical storage system, a primary storage device interposed between a secondary storage device and a data processing apparatus has a restoring unit. When at least two current storage units, which configure a logical volume and are in the mirroring relationship, concurrently fail, the restoring unit reads out data recorded in a logical volume of the current storage units from a virtual logical volume of the secondary storage device, records the data on the at least two spare storage units, thereby restoring, on the spare storage units, the logical volume of the current storage units. Even when a plurality of storages configuring a logical volume and being in the mirroring relationship concurrently fail, it is possible to immediately restore the logical volume without the maintenance operation or the like.

摘要： The present invention relates to a storage device which is defined by a logical volume, and makes it possible to perform processing, such as duplication of a logical volume, without using environmental construction and hardware resources of a host server side. The storage device has a storage part (a storage), which is constituted by a recordable storage medium and is defined by one or a plurality of logical volumes, and a storage control part (a storage server) which controls operation of the storage part. For control of the operation of the storage part defined by the logical volume, management information which is stored in a data base part (a data base) is referenced.

摘要： Once accepting an interrupt, the control is such as to not accept any interrupt including that of the highest priority within the group to which the interrupt about to be processed belongs by referring to the interrupt management table 41 (S12 shown by FIG. 7). Then, the vector number for the highest priority in the group from among the received interrupts is selected (S14 shown by FIG. 7). Then the processing of a handler for the selected vector number is executed (S15 shown by FIG. 7). The priority of the executed interrupt processing is reset to the lowest priority in the group (S16 shown by FIG. 7).
